Hi,
For the Best Ahi, try brushing some Cold Pressed Virgin Olive Oil on it about 20 min. prior to putting it on the Grill, this will Marinate, Moisturize and Seal it while cooking. Also, VERY high heat for just 3-4 min. per side depending upon the thickness - works every time. Hope this helps...
BTW, congrats on the Command achievement, now if you got your C-Quals, you'd be better than an Airline Capt....
So far as the Zonda goes -
Your Dreams can come true, it can happen to you...
Happy Motoring!... Jim'99
